Cultural Tip
In many Spanish‑speaking countries it is customary to ask about allergies before a meal, especially in schools, restaurants, and family gatherings. ‘Frutos secos’ covers almonds, walnuts, hazelnuts, pistachios, and also dried fruits like raisins, so be specific if you need to exclude only certain nuts. When speaking about a person’s condition, you can also use the adjective ‘alérgico/a’ (e.g., ‘es alérgico a los frutos secos’).
